There is a lot of information about tires and different brands, alternatives, reproductions (Coker is about the only game in town for those).
Go to the search function, search "General Discussion" , subject only, with "tire Nirvana" and you will get a large amount of information and opinions.
You can further search "general discussion", subject only, with "tire" and get even more.
I went with the Coker 185R14 repros several years ago, these are Phoenix, I do not beleive there is a Continental available, but I have not looked lately.
